Rider Assistance Control Using Shared Surrounding Vehicle Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straddle-type vehicles, due to their compact size, face challenges in securing space for surrounding environment detectors, necessitating a method to assist riders without such detectors.
Innovation Solution
A controller and control method that utilize information from a surrounding environment detector-equipped vehicle to assist a rider in a detector-less vehicle, leveraging wireless communication to transmit and execute rider-assistance operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a surrounding environment detector is mounted on a straddle-type vehicle to detect position-related information of surrounding target objects, then rider assistance capability is improved, but the device complexity and mounting space requirements increase
Solution Approach 1:
The patent introduces a server as an intermediary that collects surrounding environment information from detectors on other vehicles and transmits this information to vehicles without detectors. This mediator approach allows the vehicle without a detector to still access surrounding environment data, resolving the contradiction between maintaining rider assistance capability and avoiding detector mounting complexity.
Solution Approach 2:
The patent creates a virtual copy of the surrounding environment information by having the server collect data from detectors on other vehicles and transmit this copied information to vehicles without detectors. This allows the receiving vehicle to access environment data without physically mounting its own detector, thus improving rider assistance while reducing device complexity.
2Reliability
If a surrounding environment detector is installed to provide surrounding environment information, then safety is improved, but the vehicle body space requirements are increased
Solution Approach 1:
The server acts as a mediator that aggregates surrounding environment information from multiple vehicles equipped with detectors and redistributes this information to vehicles without detectors. This eliminates the need for each individual vehicle to mount its own detector, thereby maintaining safety through information access while eliminating the volume burden of physical detectors on compact vehicles.
Solution Approach 2:
The server provides a universal information service to multiple vehicles simultaneously, allowing any vehicle in the network to access surrounding environment information regardless of whether it has its own detector. This multi-functional approach ensures that compact vehicles can still achieve safety benefits without dedicating space to detectors.
3Reliability
If surrounding environment information is shared between vehicles through wireless communication, then rider assistance for detector-less vehicles is improved, but information transmission complexity increases
Solution Approach 1:
The server serves as a communication intermediary that centralizes the collection, processing, and distribution of surrounding environment information. Instead of requiring direct peer-to-peer communication between vehicles, the server mediates all information exchange, which simplifies the communication architecture and reduces the complexity individual vehicles must handle while improving information availability.

AI summary
The present disclosure provides a controller and a control method capable of assisting a rider in driving a straddle-type vehicle to which mounting of a surrounding environment detector is difficult. A first straddle-type vehicle (200) has a first rider-assistance system (110) that is configured to assist a first rider (101) in driving a first straddle-type vehicle (200) and has no surrounding environment detector. A second straddle-type vehicle (100) has a second rider-assistance system (10) that is configured to assist a second rider (1) in driving the second straddle-type vehicle (100) and has a surrounding environment detector (11). The first rider-assistance system (110) receives information, which is based on surrounding environment information of the second straddle-type vehicle (100), from the second rider-assistance system (10) directly or indirectly by wireless communication and executes a rider-assistance operation to assist with the first rider (101) based on the information.
